ASHRAE Standards for HVAC Testing

ASHRAE standards are the backbone of HVAC system testing, ensuring systems perform efficiently, maintain indoor air quality, and meet energy use goals. These guidelines cover key areas such as airflow, temperature, humidity, and duct leakage testing. They also establish protocols for inspections, maintenance, and energy audits for both residential and commercial buildings.

Key highlights include:

  • Energy Audits (Standard 211): Three audit levels to assess energy-saving opportunities.
  • Ventilation & IAQ (Standards 62.1 & 62.2): Minimum ventilation rates for commercial and residential spaces.
  • Duct Testing: Updated requirements for low- and medium-pressure ducts to minimize energy loss.

ASHRAE standards also guide system commissioning for new constructions and retrofits for older systems, ensuring compliance with performance and safety benchmarks. Whether for residential or commercial applications, these standards help technicians evaluate, maintain, and optimize HVAC systems effectively.

“An Overview of Ashrae Standard & its Applications”

Main ASHRAE Standards for HVAC Testing

ASHRAE has developed several key standards that form the backbone of professional HVAC testing practices. These standards outline the necessary requirements and procedures to ensure HVAC systems function effectively, delivering the desired levels of thermal comfort, energy efficiency, and indoor air quality in both new and existing commercial buildings. Below is an overview of the primary standards and their specific roles in HVAC testing.

ANSI/ASHRAE Standard 180: Inspection and Maintenance

ANSI/ASHRAE Standard 180 establishes the minimum requirements for inspecting and maintaining HVAC systems. Its goal is to help professionals maintain system performance through a structured maintenance program. This includes creating a detailed inventory of equipment, documenting information such as manufacturer details, location, capacity, and system identifiers. The standard also differentiates inspection tasks – like testing and condition checks – from maintenance tasks, which involve cleaning, aligning, lubricating, adjusting, and making necessary corrections.

Additionally, it emphasizes the importance of regular reviews, such as startup meetings and annual assessments, with more frequent checks if any system degradation is observed. These guidelines ensure that HVAC systems are maintained not only for efficiency but also to meet ventilation and indoor air quality requirements.

ANSI/ASHRAE Standards 62.1 and 62.2: Ventilation and Indoor Air Quality (IAQ)

ANSI/ASHRAE Standard 62.1 focuses on ventilation and indoor air quality requirements for commercial buildings. It defines minimum ventilation rates based on factors like building occupancy and function. The standard also provides methods for calculating outdoor air requirements and evaluating ventilation effectiveness.

For residential applications, ANSI/ASHRAE Standard 62.2 sets guidelines for whole-house ventilation and local exhaust systems. These requirements take into account variables such as home size, occupancy levels, and local climate conditions. Both standards offer performance-based compliance options, giving flexibility while ensuring that essential health and safety standards are upheld.

ANSI/ASHRAE Standards 211 and 100: Energy Audits and Performance

Energy audit and performance standards complement the above by addressing energy consumption and efficiency. Standard 211 outlines three levels of energy audits:

  • Level I: A preliminary assessment to identify quick energy-saving opportunities.
  • Level II: A more detailed analysis, including financial and energy evaluations.
  • Level III: A comprehensive engineering study with detailed project plans and cost estimates.

Meanwhile, Standard 100 focuses on energy performance by setting specific performance targets and establishing baseline energy usage. It also provides guidelines for ongoing commissioning and tracking improvements over time. Together, these standards support continuous efforts to optimize energy use and improve overall building performance.

HVAC Testing Methods Based on ASHRAE Standards

ASHRAE standards provide a framework for testing HVAC systems to confirm they meet design specifications, operate efficiently, and maintain indoor air quality. Certified technicians follow these protocols to evaluate system performance and detect potential issues before they impact a building’s overall efficiency. These testing methods ensure HVAC systems align with ASHRAE guidelines, achieving energy efficiency and air quality goals. Below are the primary testing methods based on these standards.

Airflow and Ventilation Testing

Measuring airflow is a critical step in verifying an HVAC system’s performance. Technicians use specialized instruments to assess airflow at various points in the system, comparing the results to ASHRAE’s recommended outdoor air intake rates. These rates are calculated based on the building’s occupancy and intended use, ensuring proper ventilation and air quality.

Temperature and Humidity Testing

Temperature and humidity levels play a significant role in maintaining indoor comfort, as outlined in ASHRAE Standard 55. Technicians measure these parameters at strategic points, such as supply and return air vents, to confirm the system meets its design specifications. Psychrometric calculations help verify the system’s ability to dehumidify effectively during heating or cooling cycles. In some cases, data loggers are employed to monitor temperature and humidity changes over time, ensuring consistent performance within the desired setpoints.

Additionally, the integrity of air distribution systems must be maintained to prevent inefficiencies.

Duct and Building Leakage Testing

Duct leakage testing has gained importance as energy efficiency standards become more stringent. ASHRAE Standard 189.1 now mandates testing for low- and medium-pressure ducts (3-inch water gauge) in addition to high-pressure ones (4-inch WG). This update addresses a major source of energy loss, as lower-pressure ducts can leak significantly more than their high-pressure counterparts.

“I spearheaded this update because of concerns that it is very rare to have ducts greater than 4-inch pressure class to be used today, while it was very common when the original requirement was to test the leakage of ducts greater than 3-inch WG pressure class. This resulted in much less leak testing today, while standard 189.1 is attempting to reduce energy use.”
– Jeff Boldt, Director of Innovation and Quality, IMEG Corp.

The testing process involves pressurizing the duct system and measuring air leakage rates using advanced tools. ASHRAE SPC215P provides guidelines for calculating both leakage airflow and the percentage of leakage in operating systems. Testing typically begins with 20% of the ductwork, expanding to the entire system if initial results reveal significant issues.

Industry data highlights the prevalence of duct leakage. A 2015 survey by the Building Commissioning Association revealed that 75% of engineers identified leaky ducts as a major source of energy loss in U.S. buildings, with 68% reporting leakage rates of 15% or more. These findings emphasize the importance of thorough duct testing to optimize energy efficiency.

“The industry has resisted testing because of the additional cost involved. But in reality, building owners can either make a relatively small payment upfront to ensure their ducts are operating properly, or they can continue to pay higher operating costs throughout the life of the building. The 189.1 updates to duct testing will help ensure that today’s buildings are operating as efficiently and cost effectively as possible.”
– Bob Reid, Former Chairman of ASHRAE Technical Committee 5.2 and Chief Engineer, SPOT (Spiral Pipe of Texas)

Building envelope leakage testing uses blower door equipment to pressurize the entire structure and measure air infiltration rates. This process identifies areas where conditioned air escapes or unconditioned air enters, allowing targeted sealing efforts. Properly addressing these leaks enhances building performance and reduces long-term operating costs.

HVAC Testing Process: Step-by-Step Guide

The HVAC testing process, as outlined by ASHRAE standards, involves detailed planning, precise fieldwork, and thorough data analysis. These steps ensure accurate results, compliance with industry standards, and actionable insights for system improvements. Professional technicians follow a structured protocol to assess performance, uncover deficiencies, and recommend solutions, all while minimizing errors and maximizing the value of the testing process.

Planning and Documentation Before Testing

Preparation is key to effective HVAC testing. This starts with reviewing system documentation, including design drawings, specifications, maintenance records, and occupancy schedules. These materials provide a baseline understanding of the system and help identify potential problem areas.

Testing schedules are influenced by building occupancy and usage patterns. For example, testing during peak occupancy can reveal how the system performs under real-world conditions, while off-hours testing allows for more controlled measurements. Weather conditions also play a role, particularly for outdoor air intake and building envelope evaluations.

Instrument calibration is another critical step. Tools like digital manometers, airflow measurement devices, and temperature sensors must be regularly calibrated to meet accuracy standards. Calibration certificates ensure that these instruments comply with strict error tolerance requirements, which is essential for reliable results.

Once the planning phase is complete, the process moves seamlessly into field testing.

Field Testing Procedures

Field testing begins with a visual inspection of the system. This step helps identify and address obvious issues, such as damaged ducts, missing insulation, or malfunctioning equipment.

Baseline conditions are established by recording indoor and outdoor temperature, humidity, and barometric pressure. These initial measurements provide context for any performance variations observed during testing.

Airflow testing is conducted using traverse measurements across duct cross-sections. Technicians take readings at specific grid points to calculate average velocities. Properly calibrated tools, such as pitot tube arrays and thermal anemometers, are vital for obtaining accurate airflow data.

Temperature and humidity readings are taken simultaneously at supply, return, and outdoor air locations. Psychrometric analysis is then used to evaluate the system’s ability to condition air according to design specifications. These measurements are compared to ASHRAE standards for comfort and energy efficiency.

Pressure testing assesses the integrity of ductwork and the building envelope. Duct blaster equipment pressurizes individual duct sections to measure leakage rates, while blower door fans create pressure differentials to quantify air infiltration through the building envelope.

Analyzing Results and Creating Reports

Once field measurements are complete, technicians analyze the data to evaluate system performance. Measured airflow and temperature differentials are compared to design specifications to identify any discrepancies.

Statistical analysis, such as confidence interval evaluations, helps distinguish between normal measurement variability and actual performance issues. ASHRAE standards provide guidelines on acceptable tolerance ranges, ensuring that findings are both accurate and meaningful.

Field data is converted into standardized metrics like ventilation effectiveness, energy efficiency ratios, and indoor air quality indicators. This ensures consistency across evaluations and simplifies the interpretation of results.

Reports are then created to document the testing process, measurements, and findings. Executive summaries highlight key issues and recommendations for building owners and facility managers, while technical sections provide detailed data for engineers and maintenance teams.

To help prioritize corrective actions, issues are categorized by severity, cost impact, and compliance requirements. Immediate safety concerns are addressed first, followed by recommendations for improving energy efficiency and occupant comfort. Reports often include cost estimates, implementation timelines, and return on investment calculations to demonstrate the financial benefits of addressing identified deficiencies.

Finally, follow-up testing schedules are established to monitor ongoing performance and compliance with ASHRAE standards. Trending analysis over time can reveal gradual performance declines and help optimize maintenance intervals, ensuring the system continues to operate efficiently.

ASHRAE Standards for Different Building Types

ASHRAE standards customize HVAC testing protocols based on the type of building and the project phase. The complexity of testing depends on whether it’s a new construction project, an upgrade to an existing system, or the differences between residential and commercial applications. Let’s break down how these standards address each scenario.

New Construction and System Commissioning

For new buildings, ASHRAE standards play a key role during the design and installation phases. They guide the selection of equipment, proper system sizing, and ensure compliance with energy efficiency and indoor air quality (IAQ) requirements. Commissioning, as defined by ASHRAE, is a systematic process to confirm that HVAC systems align with the owner’s expectations and function as intended. This involves testing system components under various operating conditions, verifying automatic controls, safety features, and energy management systems. Detailed documentation ensures that the system meets performance, safety, and comfort standards.

Existing Building Upgrades and Retrofits

When it comes to older buildings, ANSI/ASHRAE/IES Standard 100-2024 provides guidelines to improve energy efficiency and system performance. This standard covers all aspects of a building, including the envelope and HVAC systems, with the goal of enhancing thermal performance and reducing energy use. Retrofit testing includes energy audits, equipment efficiency checks, and assessments based on the system’s operational history. It also outlines strategies for creating energy management plans and methods for ongoing performance monitoring, ensuring that upgrades lead to measurable, long-term improvements.

Residential vs. Commercial Testing Requirements

ASHRAE standards take a different approach when comparing residential and commercial applications. For instance, ASHRAE Standard 90.1 sets energy efficiency benchmarks for commercial buildings but excludes low-rise residential properties. Commercial systems face stricter design and testing demands, particularly in large buildings where failures can have serious consequences. Standards like ASHRAE 62.1 (ventilation) and ASHRAE 55 (thermal conditions) apply broadly but are more rigorously enforced in commercial settings. Commercial projects often require detailed performance verification and permits, while residential testing focuses on basic energy efficiency, safety, and comfort.

Aspect Residential Commercial
Energy Standards Excluded from ASHRAE 90.1 Must comply with ASHRAE 90.1
Testing Complexity Basic performance checks Comprehensive testing and documentation
Regulatory Oversight Limited requirements Extensive compliance and permit needs
Documentation Minimal reporting Detailed reports and continuous monitoring

Commercial buildings demand more frequent and detailed testing, along with ongoing monitoring and extensive documentation. On the other hand, residential testing places greater emphasis on safety, comfort, and basic energy efficiency rather than complex regulatory compliance.

Choosing between the two depends on your budget, property size, and energy-saving goals.

What Energy Audits Are and Why You Need Them

Energy Audit Basics

An energy audit is all about evaluating how efficiently your building uses energy and identifying where it’s being wasted. Think of it as a check-up for your property’s energy health, helping you figure out where your money is going when it comes to energy bills.

“An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building.” – Wikipedia

During an audit, either a professional or a homeowner inspects the property to uncover issues. This could mean noticing air leaks around aging windows, finding gaps in insulation, or realizing that your HVAC system is working overtime.

But it’s not just about identifying problems. Energy audits provide clear, actionable recommendations tailored to your specific building. These could include adding better insulation, upgrading outdated wiring, installing energy-efficient lighting, or replacing an overworked HVAC system.

In many ways, an energy audit is your starting point for making smart energy-saving choices. Instead of guessing where to invest your time and money, an audit gives you a detailed roadmap to maximize the impact of your efforts.

Why Energy Audits Matter

The benefits of energy audits go far beyond just trimming your utility bills – though that alone is a pretty compelling reason. Homeowners who follow through on audit recommendations can cut their energy use by 10% to 30%, which translates to savings of 5% to 30% on monthly energy costs. For businesses, the potential savings can climb as high as 30%.

“A home energy audit helps you identify areas where your home wastes energy, offering valuable tips to improve efficiency, lower bills, and boost comfort.” – Bianca Phillips, GoodLeap

Comfort is another big win. By tackling issues like drafts or uneven temperatures, energy audits can eliminate the frustration of that one room that’s always freezing in winter or sweltering in summer. Plus, they can address ventilation problems that might lead to mold, protecting both your property and your health.

Then there’s the environmental angle. Making energy-efficient changes in commercial buildings can cut greenhouse gas emissions by up to 30%. Every kilowatt-hour saved means a smaller carbon footprint.

“Energy audits are powerful tools for identifying opportunities to reduce electricity costs in residential and commercial settings.” – Zimmerman Electric Company

If that’s not incentive enough, the government sweetens the deal. Thanks to the Inflation Reduction Act, you can claim 30% of your energy audit’s cost – up to $150 – as a tax credit. But don’t wait too long; this credit expires at the end of 2025.

Finally, energy audits can even boost your property’s value. Energy-efficient upgrades identified during an audit can make your home or business more attractive to buyers. And when you implement the recommended changes, you might qualify for even more tax credits and rebates.

Up next, we’ll dive into the costs and considerations of tackling an energy audit yourself versus hiring a professional.

DIY Energy Audits: What They Cost and Where They Fall Short

How to Do Your Own Energy Audit

Conducting a DIY energy audit involves evaluating your home’s energy use with basic household tools. This includes tasks like checking for air leaks, inspecting insulation, and examining your HVAC system for inefficiencies.

Start by tackling the basics. For example, you can use an incense stick to detect drafts around windows and doors – just watch how the smoke moves to pinpoint problem areas. Go room by room, looking for gaps around window frames, worn-out weatherstripping, or drafts near electrical outlets. These small steps can reveal areas where energy is escaping.

Pay special attention to spots where energy loss is common. Check insulation in the attic, basement, and crawl spaces. Inspect your HVAC system for disconnected ducts or clogged filters. Don’t overlook your water heater – if it’s running too hot, it might benefit from an insulating jacket.

Some tasks, like working in the attic or repairing chimneys, might be beyond your skill level. In these cases, it’s wise to call in a professional. This initial DIY effort gives you a clearer picture of your home’s energy efficiency, but it’s just the first step.

DIY Energy Audit Expenses

Once you’ve identified problem areas, you’ll need a few tools and materials to fix them. While your time is free, here’s what you might spend to get started:

Detection and Monitoring Tools:

  • A Kill A Watt detector costs $22 and measures appliance energy use.
  • The Black & Decker TLD100 infrared thermal leak detector, priced at $49.99, helps spot temperature differences and air leaks.
  • Smart plugs and relays can monitor energy usage for various devices in your home.

Sealing Materials:

  • Caulk and weatherstripping are essential for sealing air leaks around windows and doors.
  • The Easy-Stop Weather-Stripping System is $74 per window, while foam gaskets for outlets cost just $0.10 each.
  • For fireplaces, a Draftstopper runs about $55.

HVAC Improvements:

  • Water-based mastic sealant and HVAC foil tape can patch ductwork issues.
  • Water heater insulating jackets cost between $10 and $20, and similar insulating blankets are available for older tank-style water heaters.
  • Sweep seals for exterior doors help block drafts from underneath.

Additional costs might include a fireplace sweep service, which ranges from $90 to $200, or a replacement refrigerator gasket, priced between $60 and $90.

“With a little knowledge and determination, you might be surprised by your next power bill.”

Where DIY Audits Come Up Short

DIY energy audits are a great starting point, but they have their limitations. While they can help you identify obvious issues, they often miss more complex problems that require specialized tools and expertise. For example, professional energy auditors use advanced equipment like blower doors, infrared cameras, and combustion analyzers – tools that most homeowners simply don’t have access to.

The U.S. Department of Energy highlights this gap:

“A ‘do-it-yourself’ home energy audit will not be as thorough as a professional home energy assessment.”

DIY efforts might also lead to costly mistakes. For instance, you could spend a fortune on new windows when better insulation would have solved the problem. On the flip side, over-sealing your home could create indoor air quality issues that require expensive fixes.

Another challenge is expertise. Professional energy auditors have the training to spot problems that a DIYer might overlook. They also provide specific, actionable recommendations instead of generalized advice. While professional audits involve upfront costs, they can reduce energy bills by 5% to 30% annually by pinpointing the most effective solutions.

Without tools like infrared cameras or blower doors, DIY audits often miss hidden insulation gaps, duct leaks, and even safety hazards. Professionals bring a level of precision that ensures you’re investing in fixes that deliver the most impact, rather than guessing at solutions that might not address the root issues.

Professional Energy Audits: Costs and What You Get

What Professional Energy Audits Include

Professional energy audits bring in specialized tools that most homeowners don’t have access to – think blower door tests, infrared cameras, and surface thermometers. These tools allow for a deep dive into your home’s energy efficiency.

The process starts with a blower door test, which pinpoints hidden air leaks that DIY methods often overlook. From there, the auditor evaluates your entire home, including the building envelope, HVAC systems, insulation, and even appliance efficiency. Once the inspection is complete, you’ll receive a detailed report outlining specific recommendations to improve energy efficiency and cut costs.

“Choose a provider that’s actually going to do an energy audit – not just show up and put [in] insulation. They’re actually going to pressure test the house and they’re going to certify the results.” – Greg Fasullo, Home Energy Expert, Elevation

Professional Energy Audit Pricing

The cost of a professional energy audit typically ranges from $212 to $698, with a national average of $437. However, prices vary based on factors like location, home size, and the type of audit you choose. For example, here’s a snapshot of pricing by city:

  • New York, NY: $800
  • Denver, CO: $275
  • Austin, TX: $700
  • Boston, MA: $550
  • Miami, FL: $750
  • San Francisco, CA: $300

The type of audit also plays a role in pricing. An ASHRAE Level 1 (Walk-Through Audit) costs between $150 and $200 for a typical 1,800-square-foot home. A more in-depth Level 2 (Energy Survey and Analysis) ranges from $200 to $650, while the comprehensive Level 3 (Detailed Analysis and Improvements) runs between $650 and $900. On average, costs per square foot fall between $0.08 and $0.50, depending on your home’s complexity and local market rates.

Financial incentives can help offset these costs. For instance, the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement Credit covers up to $150 for home energy audits. Many utility companies also offer rebates or even free audits to their customers.

Why Professional Audits Pay Off

Investing in a professional energy audit can lead to noticeable savings. Homeowners can reduce energy bills by 5%–30%. Most people recover the cost of the audit within 6 to 12 months, with savings continuing to add up over time. Since heating and cooling often make up as much as 50% of your energy bill, even small improvements can have a big impact.

The advanced tools used in these audits reveal inefficiencies that are impossible to detect without professional help. This ensures that your money goes toward fixes that make the most difference, rather than relying on guesswork. Audits also provide a prioritized plan for upgrades, focusing on the most cost-effective changes.

“A professional assessment provides a roadmap to cost savings and enhanced comfort.” – U.S. Department of Energy

Beyond energy savings, there’s a boost to property value. Energy-efficient homes are becoming increasingly attractive in the real estate market. Professional audits not only help you save money but also reduce wasted energy and suggest eco-friendly solutions. Interestingly, while only 9% of surveyed homeowners had undergone an energy audit, those who did gained access to expert advice that goes far beyond basic weatherproofing.

Which Energy Audit Option Is Right for You

Deciding between a DIY energy audit or hiring a professional depends on your budget, the complexity of your home’s energy systems, and the level of savings you’re aiming for.

When DIY Energy Audits Make Sense

A DIY energy audit is a great starting point if you’re working with a limited budget or looking for quick fixes. New homeowners, in particular, can use this approach to get a basic understanding of their property’s energy performance. With just a flashlight, thermometer, and a simple checklist, you can spot obvious issues like drafty windows and doors – without spending a dime.

This method is especially useful for smaller homes with straightforward energy systems or when you’re planning minor upgrades rather than large-scale renovations. DIY audits are effective for identifying visible problems such as air leaks.

That said, a DIY audit should be seen as a preliminary step. While it’s helpful for catching surface-level issues, it often misses hidden inefficiencies that require advanced tools to uncover.

When to Hire a Professional

For more complex situations – like older homes or when your energy bills seem unusually high – bringing in a professional is the smarter choice. Experts come equipped with advanced tools, like blower door tests and infrared cameras, to pinpoint hidden energy losses that a DIY approach simply can’t detect. As Greg Fasullo, a Home Energy Expert at Elevation, explains:

“Most consumers don’t recognize that engaging with their energy and managing it can save you thousands of dollars a year”.

Professional audits are particularly valuable after purchasing a home or when planning major renovations. They also often qualify you for utility rebates and incentives, adding another layer of savings.

“You just can’t do it as well as a professional, and many times you’ll just waste your time.”
– Greg Fasullo, Home Energy Expert, Elevation

While professional audits typically cost between $100 and $500, the potential savings – ranging from 5% to 30% annually – can make the upfront investment worthwhile. To put it in perspective, homeowners can lose $200 to $400 a year due to air leaks alone. Addressing these inefficiencies could lead to significant long-term savings.

Once your audit identifies areas for improvement, the next step is implementing the recommended solutions to maximize energy efficiency.

DIY audits are budget-friendly, typically requiring little more than tools and items you already have at home. However, they might miss hidden inefficiencies that could quietly drain hundreds of dollars from your wallet every year.

On the other hand, professional energy audits involve a higher initial expense, ranging from $100 to $1,650, with an average cost of about $416. While the price tag might seem steep, these audits often pay for themselves within the first year through reduced energy bills. Professional auditors use specialized tools and techniques to uncover inefficiencies that a DIY approach might overlook.

For example, standby power – sometimes called “vampire energy” – can account for around 10% of your electricity bill. Fixing issues like drafts could cut your energy use by 10% to 20% annually. These kinds of targeted fixes not only reduce your energy costs but also make your home more efficient and comfortable.

Another benefit? An energy-efficient home can be a strong selling point, potentially increasing your property’s resale value. Whether you choose to go the DIY route or hire a professional, the most important step is acting on the findings. Over time, the savings from addressing energy inefficiencies often outweigh the initial costs, giving you a solid return on your investment. By taking proactive steps – whether small or substantial – you can ensure your home is running as efficiently as possible.

FAQs

What tools and techniques set DIY energy audits apart from professional ones?

When it comes to DIY energy audits, you’re mostly working with basic tools like a flashlight, a thermometer, and your own sharp observation skills to spot issues. On the other hand, professional energy audits take things to a whole new level with specialized tools. These include blower doors to pinpoint air leaks, infrared cameras that reveal insulation gaps, airflow meters for checking ventilation, and combustion analyzers to evaluate how efficiently your heating system is running. With these advanced gadgets, professionals can dig deeper to uncover hidden energy problems and provide a much more accurate picture of your home’s energy efficiency.

How do government incentives and rebates make professional energy audits more affordable?

Government programs offering incentives and rebates can help cut the upfront costs of professional energy audits, making them more accessible for both homeowners and businesses. These initiatives aim to promote energy efficiency by reducing initial expenses, ultimately helping you save money while conserving energy over time.

Taking advantage of these opportunities not only lowers your initial outlay but also boosts your overall return on investment through potential energy savings and enhanced efficiency. Check out local, state, and federal programs to see what options are available in your area.
